Central Government's responsibilities include:

Setting and collecting all taxes, except council tax
The National Health Service, state benefits such as unemployment benefit, tax credits and state pensions, making and reviewing UK law the Country's security.

The same can be applied to global and local variables, in the fact that local variables have local scope and exist in the function or method that they are in.

Global variables have global scope; this means that they can be used and referenced anywhere within your web development services code.

As in real life you wouldn't be happy if the National government dictated that everyone in a particular areas had to have their bins emptied on a particular day.

I hope that this has explained one of the basic principles of global and local variables.

Let me know in the comments about your experiences with the global and local scope.
